WINDOW VENTILATOR. 1

Application filed October 23, 1925. Serial No. 64,401.

My invention relates to a new and useful improvement in a window ventilator and has forits object the provision of a ventilator of this class, which will be simple in structure, economical of manufacture and highly eflicient inuse.

Anotherobject of they invention isthe provision of a window ventilator of this ,class, adapted for use with a. window sash having an openingformedtherein and com prisinga pair of vanes radiating outwardly from. a rotatably mounted sup-porting rod, one of the ends being imperforatedand the other being perforated, so that the opening in the window sash may be opened and closed, at will. i

7 Another object of the invention .is the provision of a shield fora window sash opening of this classwhich will be easily attachedand serve as an efiective means for shedding water.

Another object ofthe invention is the provision of rotatable closures for the opening formed in a-window Shield, asdescribed, so arranged and constructed as to be. easily removable fromfthe opening and separable from: each other.

Other objects will'appearl hereinafter.

The invention consists in the combination and arrangement'of parts hereinafter described and claimed.

The invention will be-best understood from a reference to the accompanying drawings, whichfor n. a part of .this specification,and,in which, 7 V

As shown in the drawings, the invention is adapted forv use with a window sash 9 having a lower rail 10 provided with an elongated opening 11. Thisopeningis provided with. apoc'ket'12 which ispositioned mane side of the opening and in alignment viitha epenmeii formed in i 2,'which wingers i";

10. A red 14: is secured to an imperforate strip 16 along the longitudinal axis thereof. -The rod projects beyond the. ends of the imperforated strip 16 to provide the projecting portion .17 at one side and a longer projecting portion 18 at the opposite side. Mounted onthe rod 14, adjacent the projection 17, is a collar 19 As shown in Fig. 5, the strip 16 'is'provided, adjacent its longitudinal axis, with a longitudinally eX- tending slot 20, which is parallel to and slightly spaced from the longitudinal axis of the strip 16. A perforate strip,for screenportion 21 is provided which has, at one side, a slit 22, and at the opposite side, a shorter slit 23'. The arrangement is such that the screen strip 21 may be inserted into the slit 20 of the strip 16 and slid longitudinally thereof to bring the strip 16 into engagement with the slit 22, this movement permitting the positioning of the screen strip 21 rel'ativelyjt'o the strap 16, so that the strip Q/llmay be slid longitudinally of the strip 16, to permit the strip-16to ngage in the slit 23. The supporting rod 14 is then secured welding, soldering, 'or in any other .suitable manner, to the strip l6 at its longitudinal axis: Thestrip 16 has its edges covered with a vieldable material 24, such as leather, rubber, cloth, etc. Po-

sitioned on the longer extension 18 is a coil spring 25., The structure iss-uch that, when assembled in the manner indicated, the

the device may be turned into the position shown in Fig. 2,,the lining 24 on the member 16 serving. to effects. moresecure closure. When it is desired to use the device as a ventilator, the rod, 14 may be rotated ninety degrees: from the pee ion shown in the creen imperforate member.

member into closing position for the opening 11.

Mounted over the opening 11 is a shield 26, having one end 27 angularly turned and seated in a recess 28 formed in the rail 10. By seating the angularly turned end in the recess 28, a seepage of water or other moisture behind the flange or angularly turned end 27 is prevented. The outer edge of the shield 26 is also angularly turned as at 29 for the purpose of reenforcing, a suitable end wall 30 serving to close the opposite ends of the shield.

It is evident that the device may be easily and quickly mounted in a window rail. after the necessary openings and recesses have been formed. This is a desirable feature inasmuch as the parts may be quickly and easily replaced after being wor While I have illustrated and described the preferred form of structure, I do not wish to limit myself to the precise form of structure shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

, 1. A ventilator of the class described, adapted for mounting on a window sash,

comprising a rod positioned in an opening formed in the lower rail of said sash; an imperforate strip mounted on said rod and projecting diametrically outwardly therefrom at opposite sides thereof, said member beingofsufficient-size to close said opening; a screen member mounted on said imperforate member and projecting outwardly therefrom, in'a plane other than the plane of said imperforate member at opposite sides, said screen member being of sufficient size to close said opening, said rod being rotatably mounted. I v

2. A window ventilator of the class described, adapted for mounting in an opening formed in a window sash, comprising;

an imperforate member of substantiallythe same size as saidopening; a rod secured to said imperforate member and extending longitudinally thereof, along the longitudinal axis thereof, said rod projecting at oppo site ends beyond the ends of said member, said sash being provided with aligning pockets at opposite sides of said opening for the reception of said projecting ends of said rod; and a perforate member of substantially the size of said openingsecured along its longitudinal axis to said imperforate member at one side of said rod and lying in a plane other than the plane of said 7 3. A window ventilator of the class described, adapted for use with a window rail having an opening formed therein, comprising;an imperforate member of substan= recesses; a screen member secured at its longitudinal axis on said imperforate mem her, said screen member being of substantially the same size as said opening and lying in a plane other than the plane of said imperforate member. V

f. A ventilator of the class described, com

prising an imperforate member having a longitudinally extending slit formed therein. parrallel to, and spaced slightly from, the longitudinal axis thereof and terminating within the marginal limits of said'membe'r,

said member being of substantially the same size as said opening; yieldable material covering the edges of said imperforate member; a supporting rod extending longitudi nally of and secured to said member at its longitudinal axis, said supporting rod projecting beyond the ends of said imperforate member, said opening having aligning recesses formed in opposite sides for'receiving said projecting ends, said supporting rod being rotatably mounted in'said recesses; a perforate member having a longitudinally extending slit formed in opposite ends, one of said slits being longer than the other for permitting the mounting of said perforated member in the slit formed in said imperforatemember on one ofthe projecting ends of said rod for forcing the opposite end into its recess; and an abutment mounted on said rod for limiting the thrust of said projecting end into said recess;

5. A ventilator of the class described,

adapted for use with a window frame, having an opening formed therein, comprising a shleld extending outwardly over sald opening and thence downwardly to provide a water shed, the attached edges of said shield,

being countersunk in said sash; and imperforate member having alongitudinally ex tending slit formed therein, longitudinally thereof, parallel to-and spaced from its longitudinal axis, said slit terminating within the marginal limits of said member; a perforate member having a longitudinally extending slit formed in each end, said perforate member being insertable in said slit formed in said imperforate member; yieldable material secured on the edges of said imperforated member; a supporting .rod

secured to said imperforated member at its longitudinal axis and projecting beyond the ends of the same at opposite sides, said sash having aligning recesses formed in said opening for the reception of said projeet= ing ends of said rod, one of said projecting ends being shorter than the other and one of said recesses being deeper than the other; a spring mounted on the longer of said projecting ends and adapted for forcing the shorter of said projecting ends into the shallower of said recesses; and a collar mounted on said rod for limiting the thrust of said shorter end into said recess said rod being rotatably mounted in said recesses, In testimony whereof, I have signed the foregoing.
